The principal elements that increase in abundance as a magma melt cools to ~ 600 degrees Celsius are Si, Na, and K.

In order for sedimentary rocks to be deposited and stored in the rock record, subsidence of a sedimentary basin needs to occur.

1. Examine the figure below, and determine where do you think most of the sediment is being deposited and stored?

If you identified the mineral quartz in a sample of igneous rock, what other minerals might you expect to find in that same sample rock?

Looking at the figure below, what causes the sedimentary rocks to melt at lower temperatures than the surrounding dry mantle rocks at a convergent margin?

Using the Figure below, quartz grains that are very well rounded would expected to be found in which depositional setting?

Which of the following Igneous rocks form at the highest temperature ?

Which Igneous rocks are most likely to form at a convergent plate boundary?
